Out of 6 locks, 2 of their keys worked on my Quadra 950, one was slightly better than the other. So, that gives you a little over 66% against the keys working on your computer if the lock numbers don't match. Sample size is small, so who knows the actual odds. As for re-keying: Here's what I...

I have a contribution to your project: I just bought 6 sets of NOS locks and keys on eBay for the ANS for $6.95 ea + $5.95 shipping and whatever random tax eBay tacks on. One has your name on it. - My cost exactly plus how ever you want it shipped. Also, there should be a key number on the...

I snagged all of them. I'll have extras, but my goal is to rebuild a Quadra 950 lock which is missing they key since these use the same keyways. https://www.ebay.com/itm/297309508268 I'll have extras and you know how much I paid, so if anyone wants one, send me a message. I should have them...

Odd. Ok, I tried it on my mac and it failed. Might have been zip doing it instead of Stuffit. I'll have to beat on it and see if I can replicate the error. That way I'll know what not to do at least.

Odd. I created the archive on a Quadra 950 with System 7.5.3. If it gets extracted on a modern system, it will strip the resource forks from some of the files and make it unable to compile. Not that it matters, I don't expect other people to compile and run it since I just posted it for...

I just released the source to the AMUG Internet Installer (ca 1995) via Macintosh Garden. https://macintoshgarden.org/apps/amug-internet-installer MIT License. Have fun! (Also attached here for archival sake)

So, not wanting to wait for Mouser to catch up and process my order after the storm, I dug through my cap pile and found two Nichicon VX(M) 1000uf 16v general purpose caps. Those are EOL, but they were close enough for now. I pulled and tested ESR and Capacitance of all the caps on the input...

Let's wait on Mouser. I'd like to test them before I pass the list along. I found this older list after I ordered mine: https://www.digikey.com/en/mylists/list/TMYLHKE4FN

Taking it apart for the first time was a bit complex. It was also pretty dirty, so cleaning it and decontaminating the input board took a little while. The longest part was figuring out appropriate replacements for the caps that were in it. At this point, I am waiting on new caps from Mouser...

Quadra 950 Power Supply, Input Board: This one had two leaking caps. Unfortunately, Delta populated C905A and C905B with 16 V, 1000 µF Rubycon VXB electrolytics, a series so prone to leakage that Rubycon later advised manufacturers to stop using remaining stock. As for this board, I pulled all...

Nice! I have a Iisi board that has a bad serial ports and I don't have a replacement 85C80, but I do have a few SIMMS I can borrow the chips from. I might just have to give it a try.

Interesting. This is a prototype and has some programmable logic on it that's probably a different from the final release.

Here's the second one (Prototype Quadra 700)

Here's one from a Prototype Quadra 700:

I have a prototype Quadra 700 and a release version. If you'd like, I can run it on both systems.

A little while I spent way too much time beating on a few of those boards. I played musical ram, pulled and tested all the caps, etc., but never got a single one to work. Finally, I moved the ASIC to a known-good board and it failed. The one from the good board fixed the bad one. I gave up...

If you have access to a scope, check and see if the nubus clock is there, it should be 10MHz. Also, if all the clocks and voltages check out, I poke at all the pins on the SMD chips with a dental pick looking for loose pads. It's more common than you'd think. Finally, and I am not sure how...

I wrote this a while ago for Low End Mac, but it might be applicable to your situation: " I was troubleshooting a DaynaPORT NuBus Ethernet card that wouldn’t link to a modern switch on RJ45. It would start the handshake, time out, retry… Déjà vu.. I ran into the exact same thing with an Asante...

Nice! If only I had that a few months ago when I had to figure out a few things the Bomarc schematic didn't cover that well...
